Phytochemical and spectroscopic analyses using LC\u2010MS\/MS, UV\u2013visible spectroscopy, FTIR, HR\u2010TEM, and XRD confirmed that bioactive constituents such as polyphenols and L\u2010canavanine acted as both reducing and stabilizing agents during the synthesis of FeNP\u2010CC, resulting in nanoparticles with a nanocrystalline core\u2013shell morphology. Adsorption experiments revealed that Cr(VI) removal followed pseudo\u2010second\u2010order kinetics, suggesting a chemisorption\u2010dominated mechanism. Equilibrium studies fitted best to the Freundlich isotherm model (\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    = 0.99), indicating multilayer adsorption on a heterogeneous surface. Optimal removal (100%) was achieved for 10 mg\/L Cr(VI) within 50 min under acidic conditions. Furthermore, FeNP\u2010CC successfully remediated complex, real\u2010world laboratory wastewater containing 30 mg\/L Cr(VI) despite competitive matrix interferences. Overall, this biogenic nanobiosorbent represents a highly sustainable, low\u2010cost, and efficient candidate for practical wastewater purification.\n                  <\/jats:p>","DOI":"10.1002\/cbdv.71847","type":"journal-article","created":{"date-parts":[[2026,10,21]],"date-time":"2026-10-21T06:35:10Z","timestamp":1792564510000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bioengineered Iron Nanoparticles From\n                    <i>Canavalia cathartica<\/i>\n                    Seeds: A Promising Nanobiosorbent for Cr (VI) Remediation"],"prefix":"10.1002","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7685-9204","authenticated-orcid":false,"given":"Neethu","family":"Cyril","sequence":"first","affiliation":[{"name":"Department of Chemistry Assumption College  Kottayam Kerala India"},{"name":"School of Environmental Sciences Mahatma Gandhi University  Kottayam Kerala India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"James Baben","family":"George","sequence":"additional","affiliation":[{"name":"Department of Chemistry St. Berchman's College  Kottayam Kerala India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sylas","family":"Variyattel Paulose","sequence":"additional","affiliation":[{"name":"School of Environmental Sciences Mahatma Gandhi University  Kottayam Kerala India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laigi","family":"Joseph","sequence":"additional","affiliation":[{"name":"Department of Chemistry T.M.J.M Government College, Manimalakunnu  Oliyapuram P.
